how to repair engine code p0320 on 03` navigator?

Answer 1

that code is for the crank sensor, located on the front of the engine down and almost next to the harmonic balancer (bottom pulley). If you replace it yourself remember to clear the codes after replacing the sensor. good luck

Answer 2

do a bit of your own diagnostic work. there is a way for you to display the codes for the problem and to see what that code means. do some googling for chrysler emissions codes. follow the instructions you find precisely. also, I have never found a dealer or repairman who could get a problem right the first time, consistently. ask the service rep at the shop if he will have his tech guy look at the codes again and see what might still be wrong. one dealer I went to 'tested' my car twice and the light kept coming on. I took one look and saw that one of the emissions control hoses was worn through right on top of the strut mount. the problem was in plain view, but they were so sure the problem was somewhere else, they were blind to the obvious. you can clear the code yourself again, probably by disconnecting the negative on your battery for 30 seconds, then reconnecting. You'll have to reset your presets on the radio, but the check engine light will probably go out, again, temporarily. Maybe permanently. Sometimes my light comes on and stays on for a few days while I use the ignition the required number of times for the code to clear, then no problem thereafter. In any event, the problem isn't likely to be anything that will hurt your engine, but it is annoying, isn't it?

Answer 3

Take it to a mechanic who knows how to diagnose problems based on the code. That's a crank position sensor code if memory serves. Knowing that is only a starting point.

You need to use that information to troubleshoot the cause of the code. Is it a bad sensor, corroded connection somewhere in the wiring harness, pinched or cut wire somewhere, bent crank or one of several other possible causes? You can't just start swapping parts in hope of getting lucky.

Answer 4

bring it to a repair shop they should tell you what the code is most auto parts stores will not be able to get the code for your 03 it has a CAN network that most scan tools will not read

Answer 5

This is a crankshaft sensor code. Try replacing it. Near the front crankshaft dampner
